    1.17 +// Test case code for checking current behaviour of graphics_openglesheaders
    1.18 +// The purpose of this source code is to thrown an error during compilation
    1.19 +// if the GLES/egl.h header does not re-direct to the system-wide EGL/egl.h
    1.20 +// The use of GLES/egl.h is a legacy, and kept to ease the transition of
    1.21 +// applications to using EGL/egl.h instead.
    1.22 +// This code must be compiled without the legacy setting
    1.23 +// __OPENGLESHEADERS_LEGACY_EGL_1_1 to ensure that GLES/egl.h re-directs
    1.24 +// to the system-wide EGL/egl.h
